Strongly coupling chiral molecules to circularly polarized light in an optical cavity give the two mirror-image forms of these different energies, suggesting a viable way differentiate between them.

Very recently, Grushevsky continued D’Hoker and Phong’s program of finding the chiral superstring measure from first principles by constructing modular forms satisfying certain factorization constraints. He has proposed an ansatz in genus 4 and conjectured a possible formula for the superstring measure in any genus, subject to the condition that certain modular forms admit holomorphic roots. In...

(-)-gephyrotoxin-223 was formally synthesized from chiral synthon 1 which has been chemoenzymatically synthesized  in the presence  of candida antartica lipase.

The current constraints from lattice QCD on the existence of the H-dibaryon are discussed. With only two significant lattice QCD calculations of the H-dibaryon binding energy at approximately the same lattice spacing, the forms of the chiral and continuum extrapolations to the physical point are not determined. In this brief report, we consider the constraints on the H-dibaryon imposed by two s...

I make a number of observations concerning discretization errors in twisted-mass lattice QCD that can be deduced by applying chiral perturbation theory including lattice artifacts. (1) The line along which the PCAC quark mass vanishes in the untwisted mass-twisted mass plane makes an angle to the twisted mass axis which is a direct measure of O(a) terms in the chiral Lagrangian, and is found nu...

A photochromic diarylethene having 2-methyl-4-pyridyl groups formed chiral cocrystals with (R)- or (S)-1,1'-bi-2-naphthol (BINOL). X-ray crystal structure analysis revealed that the diarylethene forms O-H···N type hydrogen bonds with BINOL and the central hexatriene moiety is fixed in P- or M-helix conformation in the cocrystals. The diarylethene molecules underwent reversible cyclization react...

In the physical vacuum of QCD, the energy density of lightquark fields strongly coupled to slowly varying gluon fields can be negative, and so a condensate of pairs of quarks and antiquarks of nearly opposite momenta forms which breaks chiral symmetry, confines quarks, and makes gluons massive.

Strecker reaction is one of the simplest multicomponent reactions. It used for synthesis of chiral α-amino nitriles. This reaction was carried out in the presence of catalytic amount of layered double hydroxides (LDHs). In this study, simple and practical method for the synthesis of this class of catalysts is provided. The results shown that LDH is the good heterogen catalyst for synthesis of c...

The high performance liquid chromatography (HPLC) enantioseparation of four β-blocking agents metoprolol, bisoprolol, propranolol and atenolol was performed on amylose tris-(3,5-dimethylphenylcarbamate) chiral stationary phase using n-hexane-ethanol-diethylamine (DEA) as the mobile phase and related chiral recognition mechanisms were discussed. Enantiomeric separation of the fourβ-blockers was ...

Two chiral structural isomers have been synthesized by molecular engineering of L-tartaric acid. In the presence of LiOH isomer forms a thermally stable, fluorescent gel which exhibits interesting nano-cluster morphology, anomalous optical and rheological properties whilst forms a non-fluorescent solution under similar conditions. The current-voltage (I-V) curve followed a non-linear trend, rat...
